BACKGROUND OF THE INVENTION

[0001] The present invention relates to a fence. More particularly, theinvention relates to a fence capable of adapting to any angle ofinclination comprising a plurality of columns, horizontal connectingmembers which have more than one degree of freedom through a connectingmeans between a pair of columns and vertical connecting members whichare connected to the horizontal connecting members.

[0002] In general, the conventional fence comprises a plurality ofcolumns which act as a structurally supporting member, horizontalconnecting members and vertical connecting members which are connectedto each other. The fence is usually made of metal or plastic and isconstructed on the outside of a house or building in order to protectfrom intrusion as well as to define a perimeter.

[0003] However, the conventional fence can not easily be constructed ona ground with a degree of inclination due to its interconnectedstructure between horizontal connecting members and vertical connectingmembers. As a result, a separate fence that fits the inclination of theground has to be manufactured.

[0004] Korean Utility No. 201549 discloses an assembly fence whichcompensates the above mentioned weakness. As shown in FIGS. 1a and 1 b,the disclosed fence comprises a circular column 11 which fixes theassembly fence firmly on the ground, a rail 21 which connects the column11, a rail fixing bar 22 which joins the column 11 and rail 21, a pole31 which is fixed on the rail at regular interval 31. A curvaturesection 24 exists at one side of the rail fixing bar 22 which is incontact with the column 11.

[0005] The above mentioned fence is constructed by first joining therail fixing bar 22 with a curvature section 24 with the column 11,fixing the rail fixing bar 22 to the rail 21, joining another railfixing bar 22 with the column 11 in order to maintain a fixed angle withrespect to the rail which is fixed to the column 11, connecting anotherrail to the column 11, fixing the pole 31 which is formed by putting afront face plate and a back face plate together on the rail 21 atregular interval in order to construct a fence.

[0006] The angle of the above fence becomes fixed when the rail 21 andcolumn 11 are joined together. As a result, it can not be constructed onan uneven surface with an angle of inclination and also it is prone tocorrosion since the linkage sections are exposed to outside.

SUMMARY OF THE INVENTION

[0007] The object of the present invention is to provide a fence whichcan be constructed easily on the ground irrespective of its angle ofinclination and its linkage sections are completely protected from theoutside exposure while having a sufficient structural strength.

[0044] The vertical connecting member 300 comprises a plastic cover 330,and a metal frame 330 a which is inserted to the inside of the plasticcover 330. The metal frame 330 a has ribs 330 b which prevent atrembling movement. At the upper and lower ends of the verticalconnecting member 300, the sealing member 350 is tightly attached.

[0045] Also, the vertical connecting member 300 and horizontalconnecting member 200 are joined together by inserting a T shapeattaching member through the fixing hole that penetrates the verticalconnecting member 300 and horizontal connecting member 200.

[0046] At one side of the column and connecting means, which are joinedtogether by bolts or pieces, has some more bolts (pieces) connectingsection 290 a to be fixed by a sealing cap 290 at one side.

[0047] Hereinafter, the effects of the present invention with the aboveconstruction will be described in detail.

[0048] As shown in FIGS. 2 through 7, the column 100 and the horizontalconnecting member 200 that interconnects between the two columns 100 areprotected from corrosion due to contact with outside moisture by theplastic cover which covers the whole body of the metal frame. As aresult, the life cycle of the fence is significantly extended.

[0049] The connecting means 210 that connects between the column 100 andthe horizontal connecting member 200 is protected from a direct contactwith moisture by forming a bolt connecting section 290 a as a singlebody where a joint bolt can be inserted and a sealing cap is fixed whenthe joint bolt is installed on the bolt connecting section 290 a.

[0050] The moisture intake to the column 100 and the horizontalconnecting member 200 is prevented by tightly attaching the heads 120,310, which are formed in such a way that no accumulation of rain couldoccur, to the upper section of the column 100 and the horizontalconnecting member 200.

[0051] Furthermore, a loose movement of the column 100 is prevented wheninstalled vertically by a supporting plate 110 a-1 which is connected toa main frame 110 a as a single body. When the supporting plate isconnected to an anchor bolt which is buried under the ground, the column100 is fixed on the upper face of the ground.

[0052] On the supporting plate 110 a-1, a slit shape bolt hole is formedin order to attach tightly while maintaining a clearance between thesupporting plate and an anchor bolt 130 which is buried under theground, hence, improving the work efficiency.

[0053] At this instance, the sealing member 110 a-2 which covers thesupporting plate 110 a-1 is tightly attached on the outer surface of thecover 110 b in order to prevent any intake of moisture.

[0054] The cover 110 b and the main frame 110 a, which is inserted tothe cover, are space apart by a plurality of ribs in order to maintainthe internal space dry and to allow an easy control over setting theclearance when the cover is inserted to the outside of the frame as wellas preventing any loose movement.

[0055] Since the heads 120 comprise a first head 120 a and a second head120 b which are joined to by a linking means 160, the shape of the fencecan be changed freely by installing various types of the first head 120a on the upper face of the second head 120 b.

[0056] The user can vary the external appearance by changing the firsthead 120 a which can have various shapes. A plurality of fixing pieces160 c, which are formed around the fixed protrusion 160 b, are insertedto the fixing groove 160 f, which is formed around the supporting hole160 e and directly facing the fixing pieces 160 c, are firmly fixed by arotating movement.

[0057] The fixing pieces 160 c are firmly supported by a lodging slot160 g after being inserted along the sliding face at one side of thefixing groove 160 f. As a result, the first and second heads are tightlyattached together.

[0058] The horizontal connecting member 200 which is connected to theside of the column 100 in the horizontal direction is freely movable dueto the connecting means 210, hence, the fence can be easily installed ona ground with various degrees of inclination.

[0059] As shown in FIG. 7, when the horizontal connecting member 200 isconnected to a receiving space 210 a-1, the connecting means 210 isfixed to a column 100 using a fixing plate 210 b which is protruding asa single body from the side.

[0060] At this instance, the downwards movement of the connecting meansare prevented by a “

” shaped supporting piece which is inserted to the plastic fixing plate210.

[0061] Also, the up and down movement of the horizontal connectingmember 200 is possible by attaching it to a supporting body 210 athrough a hole 210 a-1 as shown in FIG. 6. The covering member 210 c isfixed outside of the supporting body 210 a in order to protect corrosionof the supporting body.

[0062] The connecting means 210 can freely move in omni-direction aroundthe column 100 by comprising a supporting body 210 a which has areceiving spec as shown in FIG. 3 and a fixing plate 210 b which canmove freely through a second connecting means 210 d at one side.

[0063] Also, the second connecting means 210 d allows the free movementof the horizontal connecting member 200 by comprising a fixed ball 210a-2 which protrudes from the supporting body 210 a and a fixing hole 210b-1 which is installed at one side of the fixing plate 210 b and acceptsthe fixed ball 210 a-2.

[0064] As shown in FIGS. 5b and 5 c, a decorating plate 340 is fixed atthe front side after forming a guide rail 330 a at the depressed section330 which is formed at one side of the vertical connecting member 300.At this instance, an attaching plate 340 a, whose width becomesincreasing narrower along the inside direction of the decorating plate340, is easily inserted by pressing it.

[0065] Also, the decorating plate with various colors can be inserted inorder to be able to change the external appearance of the fence. Thedecorating plate prevents exposures of bolts in order to protect themfrom corrosion.

[0066] When an external shock is applied to the decorating plate 340,the shock is absorbed by the attaching plate 340 a which protrudes fromoutside of the vertical connecting member 300 when it is installed onthe guide rail 330 a.

[0067] The shape of the head 310 is such that the water on the uppersection can freely flow downwards. The shape of the lower section issuch that at one end of the vertical connecting member 300 can easily beinserted to it.

[0068] The vertical connecting member 300 comprises a frame 330 a whichis inserted between the cover 330 and inside of the vertical connectingmember 300. It is fixed to a horizontal connecting member by a T shapedattaching member 360. Ribs are installed on the cover in order toprevent the trembling movement of the frame 330 a.

[0069] The fence according to the present invention can be constructedeasily on the ground irrespective of its angle of inclination and itslinkage sections are completely protected from the outside exposurewhile having a sufficient structural strength.

[0070] Also, the shock which traveling to the fence can be absorbedtherefore preventing the shock reaching the column.
